to list the file in the Kbuild file.
See "7.4 generic-y" for further info on syntax etc.
+--- 6.11 Post-link pass
+
+ If the file arch/xxx/Makefile.postlink exists, this makefile
+ will be invoked for post-link objects (vmlinux and modules.ko)
+ for architectures to run post-link passes on. Must also handle
+ the clean target.
+
+ This pass runs after kallsyms generation. If the architecture
+ needs to modify symbol locations, rather than manipulate the
+ kallsyms, it may be easier to add another postlink target for
+ .tmp_vmlinux? targets to be called from link-vmlinux.sh.
+
+ For example, powerpc uses this to check relocation sanity of
+ the linked vmlinux file.
+
=== 7 Kbuild syntax for exported headers
The kernel includes a set of headers that is exported to userspace.
